应用scoop工具安装最新版的，只需要打开window-terminal，然后运行：
scoop bucket add java
将java添加到scoop-bucket中，然后搜索可安装的java版本。
PS C:\Users\gaowei> scoop search openjdk
'java' bucket:

安静地等待5分钟，核实安装的版本：
PS C:\Users\gaowei> java --version
openjdk 11.0.2 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2 9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2 9, mixed mode)
PS C:\Users\gaowei> scoop which java
C:\Users\gaowei\scoop\apps\openjdk11\current\bin\java.exe
卸载java只需要一行命令：
scoop uninstall java
以上就是用scoop包管理工具安装java的方法。
